Positive or Negative Distance

Hallo there,

is it somehow possible to show whether a point is in front or behind of a wall? With Geometry.DistanceTo I only get positive values. And a normal vector will always be the same direction for a point in front or behind of a wall.


vector should be different. show your graph, it’s easier to help.

You should be able to use Vector.ByTwoPoints to determine the direction and scale.

It does kinda work, but i get a problem with the point of the surface. Becouse I want to proove multiple point but only have one reference point from the surface. When it is not rectangular to the CS it doesnt always work. (3,1 should be positive)
